Description

Technical Field

[0001] This utility model relates to the field of distillation column technology, specifically a double-layer guide plate type distillation column. Background Technology

[0002] The working principle of a distillation column is to partially vaporize a liquid mixture and separate the components by utilizing their different volatility. However, in existing distillation columns, the liquid evaporates only on a single layer of the liquid surface during operation, resulting in a small evaporation area and insignificant distillation effect.

[0003] Chinese patent discloses a double-layer guide plate distillation column (authorization announcement number CN218653026U). In this patented technology, the distilled liquid flows downward along the upper guide plate in a thin film, increasing the surface area for distillation and evaporation. The liquid outlet is connected to the inlet of a circulating liquid supply device, allowing the incompletely distilled liquid to be distilled again, thus improving the distillation efficiency through repeated circulation. The hot air circulation mechanism can adjust the outlet air temperature according to the temperature sensed by the temperature sensing element, and can quickly provide the temperature required for distillation when the distillation conditions change.

[0004] However, it has certain drawbacks: it cannot filter the hot air in the hot air circulation mechanism. During the circulation process, the hot air can easily carry dust and impurities that are already in the pipes into the cavity of the distillation tower, causing the dust and impurities to adhere and accumulate on the inner wall of the cavity, forming a thick layer of dirt, which affects the heat transfer efficiency and leads to a decrease in the effectiveness of the hot air circulation mechanism.

[0021] Please see Figures 1-3 In this embodiment of the present invention, a double-layer guide plate distillation column includes a column body 1. A heating chamber 2 is formed on the inner wall of the column body 1. Multiple guide plates 3 are arranged from top to bottom inside the column body 1. Each guide plate 3 includes a first plate 4. A support plate 5 is installed at the right end of the first plate 4, and a second plate 6 is installed at the lower end of the support plate 5. A connecting pipe 7 is connected through the interior of both the first plate 4 and the second plate 6. A through hole 8 is formed on one side of the connecting pipe 7 inside the second plate 6. A column cover 9 is installed at the upper end of the column body 1. A feed pipe 10 is connected through the front surface of the column cover 9, and an exhaust pipe 11 is connected through the left side of the upper surface of the column cover 9. An electric heating element is connected through the middle of the upper surface of the column cover 9. The heating element 12 is movably connected through the first plate 4 and the second plate 6. The heating element 12 is located inside the tower body 1. A hot air mechanism 13 is installed on the left side of the tower body 1. A first air duct 14 is installed at the air inlet end of the hot air mechanism 13, and a second air duct 15 is installed at the air outlet end of the hot air mechanism 13. The second air duct 15 is connected to the lower end of the interior of the heating chamber 2. A third air duct 16 is connected to the upper end of the left side surface of the tower body 1. The third air duct 16 is connected to the upper end of the interior of the heating chamber 2. A filter chamber 17 is installed between the first air duct 14 and the third air duct 16. The first air duct 14 is connected through the right side surface of the filter chamber 17, and the third air duct 16 is connected through the left side surface of the filter chamber 17.

[0022] A discharge pipe is installed at the lower end of tower body 1 for discharging residual materials;

[0023] The feed pipe 10 is used for material entry; the first plate 4 and the second plate 6 increase the contact time between the material and the hot air, thereby improving the distillation efficiency; the lower end of the support plate 5 has a horizontal length less than that of the second plate 6; the connecting pipe 7 is higher than the upper surface of the first plate 4 and the second plate 6, and it is used for steam discharge; the through hole 8 is used for material release.

[0024] The exhaust pipe 11 can be connected to a condenser to condense the steam into a liquid for recycling.

[0025] The electric heating element 12 is used to heat the interior of the tower body 1;

[0026] The hot air mechanism 13 includes a hot air blower and a heating unit, which are used to generate hot air flow. The air flow is discharged into the heating chamber 2 through the second air duct 15, and then discharged into the hot air mechanism 13 through the third air duct 16, thereby circulating the hot air flow. The hot air mechanism 13 further improves the distillation efficiency.

[0027] exist Figure 1 , Figure 2 and Figure 4 In the middle: A support ring 18 is connected through the upper surface of the filter chamber 17. A filter plate 19 is installed on the inner surface of the support ring 18. A cleaning mechanism 20 is provided inside the filter chamber 17 on the left side of the filter plate 19. The cleaning mechanism 20 includes a connecting plate 21. The lower end of the connecting plate 21 is installed on the lower surface of the filter chamber 17. A connecting rod 22 is rotatably connected to the upper end of the connecting plate 21. A fan blade 23 is installed on the left end of the connecting rod 22, and a cleaning plate 24 is installed on the right end of the connecting rod 22. The cleaning plate 24 is movably attached to the filter plate 19.

[0028] The filter plate 19 is used to filter dust and impurities in the hot airflow to prevent them from adhering to the heating chamber and accumulating, which would reduce the heat conduction efficiency.

[0029] The weight of the support ring 18 is sufficient to stably press the filter plate 19 into the filter chamber 17, making it easy to remove the filter plate 19 for cleaning;

[0030] The circulating airflow can drive the fan blades 23 to rotate, which in turn drives the cleaning plate 24 to rotate and clean the filter plate 19. This causes dust and impurities to fall to the lower end of the filter plate 19, preventing the filter plate 19 from clogging in a short time and extending the service life of the cleaning plate 24, thus eliminating the need for frequent cleaning.

[0031] The working principle of this utility model is as follows: During use, the operator discharges the material into the interior of the tower body 1 through the feed pipe 10. The electric heating tube 12 heats the material, and the hot air mechanism 13 generates a hot airflow. The hot airflow is discharged into the heating chamber 2 to heat the material, enabling the material to be distilled quickly. The material flows through the first plate 4 to the second plate 6, and then falls through the through hole 8, increasing the contact area and time with the hot air, thereby further improving the distillation efficiency. During the circulation of the hot airflow, dust and impurities are filtered down by the filter plate 19, preventing them from adhering to the surface of the heating chamber 2. The hot airflow impacts the fan blades 23, causing them to rotate the cleaning plate 24, cleaning the filter plate 19 and preventing it from clogging in a short time. The steam generated by distillation is discharged into the condenser for condensation and recovery treatment through the connecting pipe 7 and the exhaust pipe 11.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
